HBO Max's other distribution partners include Apple, Cox, Google Play, Hulu, Optimum, Samsung Smart TV, Spectrum, Suddenlink, VerizonFios, YouTube TV, and select independent cable, broadband and telco providers through the NCTC, including WOW!, Atlantic Broadband, RCN and MCTV.

Apple offered anyone who bought a new Apple product a free year of Apple TV Plus, which also launched in November.
